2. Receiver
2.1 Power supply
The receiver is able to operate with an on-board bat-
tery (9V E-Block) or with the supplied external
12V= power adaptor. A high-grade alkaline bat-
tery (800mAh) will allow for ca. 5 hours of contin-
uous receiver operation. When installing a new
battery, observe the correct battery polarity which is
printed on the outside of battery cavity cover. A battery
which has been installed with wrong polarity will become warm and will
discharge quickly.
2.2 Placement
The receiver should be best operated in locations which are free from spurious
electromagnetic radiation. Digital devices are often a source of stray fields that
can have a negative effect on the receiver's performance.
